Pose the laser scene and hold it still, so it can be poked at

T.laserScene() (or #laser on the URL) drops into splatter with six bodies of
different types at known depths, the laser armed, a pull held, and the world
paused.

T.pause(true) freezes the WORLD but keeps drawing, which is the whole point: a
value changed in devtools shows on the next frame while the scene stands still.
The old recipe halted rAF, which freezes the picture too and is no use for
judging how something looks.
